Problems solved by technology

However, such packages are not sufficient for dispensing multiple-component compositions in a variety of applications, particularly where only a relatively small amount of composition is needed.
However, inadequate attention to proper disinfection and handling techniques of the assembly may increase the risk of transferring an infectious disease from one patient to another.
However, a common issue with such packages is the number of steps required to obtain the multiple-component composition.
Generally, the flowable components are required to be dispensed into a series of adjacent chambers, which commonly results in an undesirable backflow of the components into previously dispensed chambers.
Backflow reduces the total amount of the available composition, and may potentially offset the relative amounts of the flowable components.

Embodiment Construction

[0026]FIGS. 1A, 1B, and 2 are respectively a top perspective view, a bottom perspective view, and a side view of a package 10 of the present invention, in use with a brush 12. The package 10 is a multi-layer device that is capable of dispensing flowable components of a multiple-component composition in a substantially simultaneous manner. This reduces the time required to mix, dispense, and use the composition. As shown in FIG. 1A, the package 10 includes a top film14 secured above a bottom film 16 at an interface 18. Dimensionally, the package 10 also includes a front end 20a and a rear end 20b relative to a dimension X, and lateral sides 22a and 22b relative to a dimension Y.

[0027]Directional orientations are used herein for the sake of clarity, and are not intended to limit the scope of the present invention. Terms such as “front” and “rear”, are defined herein as being relative to the dimension X. Terms denoting lateral orientations are defined herein as being relative to the di...

Abstract

The present invention is a packaging article that includes a first chamber defined by a sealed connection between a first film and a second film, a second chamber defined by a sealed connection between a third film and a fourth film, where the third film at least partially abuts the second film, and a third chamber defined by a sealed connection between the first film and the fourth film.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a package for storing and dispensing flowable components. In particular, the present invention relates to a package for storing separate flowable components, and dispensing the flowable components in a substantially simultaneous manner.[0002]A number of liquid and semi-liquid compositions are made from two or more flowable components that are typically not mixed together until immediately prior to use. For example, certain adhesives such as epoxies are sold in packages that initially keep components of the adhesive separated from each other. Whenever such adhesives are needed for use, the components are mixed together and a chemical reaction between the two components begins. After the components are mixed, the composition is applied to the work site before the composition unduly hardens.[0003]A number of packages have been proposed over the years for separately containing and storing components of multiple-component ...
